Bài 2: Tìm số hữu tỷ x biết rằng:
a) \(-\frac{3}{2} - 2x + \frac{3}{4} = -2\)
b) \(\left(-\frac{2}{3} \times \frac{3}{5}\right) - \left(\frac{3}{2} - \frac{10}{3}\right) = \frac{2}{5}\)
c) \(x \cdot \left(\frac{3}{5} \times 13 - 5\right) = -\left(\frac{7}{10} - x\right)\)
d) \(2x - \frac{3}{3} - 5 = 3 - x\)
e) \(\frac{2}{3x} - \frac{3}{12} = \frac{7 - 2}{9 - 6x}\)
f*) \(\frac{1}{x - 1} - \frac{2}{3} \times \frac{6}{5} = \frac{5}{2 - 2x}\)
g*) \(-\frac{3}{2} - 2x = -\frac{5}{4}\)
h**) \(\frac{1}{x - 1} = \frac{1}{12}\)
i*) \(\frac{3}{2} - \frac{7}{6} + \frac{1}{3} = 0\)
j*) \(-2x + 1 = 3\)
k) \(\frac{13}{x - 1} - \frac{5}{2x - 2} - \frac{6}{3x - 3}\)
l) \(\left(\frac{3}{2} - \frac{2}{5}\right) : x = -\frac{1}{2}\)
m) \(\left(\frac{3}{2} - \frac{2}{-5}\right) : x = \frac{3}{2}\)
n) \(\left(\frac{3}{2} - \frac{5}{11} - \frac{3}{13}\right) \cdot (2x - 2) = \left(-\frac{4}{3} - \frac{5}{22} + \frac{3}{26}\right)\)
